MODEL 2017-1351 Up/Downconverter
1.0 General
1.1 Equipment Description
The 2017-1351 L-band Up/Downconverter converts 70 MHz to 130-512 MHz (Up) and 130-512 MHz to 70 MHz (Down) in 1 MHz steps with low group delay and flat frequency response. Synthesized local oscillators (LO) provide frequency selection. Multi-function push button switches select the RF frequency, gain, and other parameters. Front panel LEDs provide indication of DC power (green), PLL alarm for up and downconverters
(red), remote operation (yellow), and Upconverter mute (yellow). Gain can be manually controlled over a -10 to +30 dB range for the upconverter and over a 0 to +50 dB range for the downconverter as adjusted by the front panel multi-function push-button switches. Remote operation allows selection of frequency and gain. Parameter selection and frequency and gain settings appear on the LCD display. Connectors are BNC female for IF and the optional external reference input and output, and Type F female for RF. LNB or SSPB +24 VDC and 10 MHz reference can be inserted on the RF lines as added options. A high stability (±0.01ppm) option is also available. It is powered by a 100-240 ±10% VAC power supply and housed in a 1.75” X 19“ X 16” 1RU chassis.

1.4 Environmental Use Information
A. Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions located in the user manual furnished by the manufacturer of your equipment rack.
B. Mechanical Loading - Mounting of equipment in a rack should be such that a hazardous condition does not exist due to uneven weight distribution.
C. Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack may be greater than room ambient temperature.
Therefore, consideration should be given to Tmra.
D. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. Additional space between units may be required.
E. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits could have on over current protection and supply wiring.
Appropriate consideration of equipment name plate rating should be used when addressing this concern.
F. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connection to the
Branch (use of power strips).
G. Top Cover - There are no serviceable parts inside the product so, the Top Cover should not be removed.
If the Top Cover is removed the ground strap and associated screw MUST BE REINSTALLED prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or EGRESS emission problems.
2017-1351 Manual, Rev. B Page 8 09/14/17
2.0 Installation
2.1 Mechanical
The 2017-1351 consists of one RF/Controller PCB housed in a 1 RU (1 3/4 inch high) by 16 inch deep chassis.
A switching, ± 12, +5, +24 VDC power supply provides power for the assemblies. The 2017-1351 can be secured to a rack using the 4 holes on the front panel. Figure 2.0 shows how the 2017-1351 is assembled.

2.4 Installation / Operation
2.4.1 Installing and Operating the 2017-1351, Upconverter Section
1.) Connect a -40 dBm to -10 dBm signal to IF In, J4 (Figure 2.1).
2.) Connect the RF OUT, J5, to the external equipment.
3.) Connect 100-240 ±10% VAC, 47 - 63 Hz to AC on the back panel.
4.) Set the desired output frequency (See Section 2.5 Menu Settings).
5.) Set the input level (See Section 2.5 Menu Settings).
6.) Set the gain (See Section 2.5 Menu Settings).
7.) (option -V) To power the SSPB (+24 VDC, 2.5 amps max) from the 2017-1351 install a
2.5 amp 1/4” fuse in F2.
CAUTION!!! INSTALLING A FUSE IN F2 PUTS +24 VDC, 2.5 AMP POWER ON THE CENTER PIN
AND MAY DAMAGE EQUIPMENT IF IMPROPERLY CONNECTED TO EQUIPMENT THAT
CANNOT HANDLE THIS VOLTAGE OR HAS A DC PATH TO GROUND.
8.) Be sure DS6 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.2).
2.4.2
Installing and Operating the 2017-1351, Downconverter Section
1.) Connect a -70 dBm to -20 dBm signal to RF In, J2 (Figure 2.1).
2.) Connect the IF OUT, J1, to the external equipment.
3.) Connect 100-240 ±10% VAC, 47 - 63 Hz to AC on the back panel.
4.) Set the desired input frequency (See Section 2.5 Menu Settings).
5.) Set the gain to get an output level in the 0 to -20 dBm range (See Section 2.5 Menu Settings).
6.) (option -L) To power the LNB (+24 VDC, 0.5 amps, max) from the 2017-1351 install a
1 amp 1/4” fuse in F1.
CAUTION!!! INSTALLING A FUSE IN F1 PUTS +24 VDC, 0.5 AMP POWER ON THE CENTER PIN
AND MAY DAMAGE EQUIPMENT IF IMPROPERLY CONNECTED TO EQUIPMENT THAT
CANNOT HANDLE THIS VOLTAGE OR HAS A DC PATH TO GROUND.
7.) Be sure DS6 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.2).
8.) AC Fuse - The fuse is a 5 mm X 20 mm, 2 amp slow blow (Type T) and is inserted in the far slot in the drawer below the AC input as shown in Figure 2.3. There is a spare fuse in the near slot.
If a fuse continues to open, the power supply is most likely defective.

Menu 13 View LNB and/or SSPB Current (options -L and/or -V)
Save Menu At the end or when “R” is selected from any of the above menus
Alarm indications appear on the LEDs (see figure 2.2).
All program changes must start with the operation of the Menu/Execute switch and must also end with the operation of the Menu/Execute switch verified by the “Save Settings?” Menu. If this sequence is not followed, none of the changes will take effect. If programming is initiated and no operator action takes place for approximately 12 seconds (before the final press of the Menu/Execute switch) the display will revert to its previous status and you will need to start over.
2017-1351 Manual, Rev. B Page 15 09/14/17
2.5.2 Power-On Settings
NOTE: THE LAST STATUS OF A UNIT IS RETAINED EVEN WHEN POWER IS REMOVED.
WHEN POWER IS RESTORED, THE UNIT WILL RETURN TO IT'S PREVIOUS SETTINGS.
When power is first applied, the LCD display goes through three steps.
1. The LCD goes black to show all segments are functioning.
2. The software version will be displayed.
R E V 1 . 0 0
3. The present frequency and gain of the up and downconverter is shown.
U F = 475 G=+10.0
D F = 140 G=+20.0
The unit is now operational and ready for any changes the operator may desire.
2.5.3 Control Switches
1. Menu/Execute - Any change to the programming of the unit must be initiated by pressing the
Menu/Execute switch and completed by pressing the Menu/Execute switch.
2. Horizontal Switch - This switch is mounted so its movement is horizontal and moves the cursor left or right.
3. Vertical Switch - This switch is mounted so its movement is vertical and has two functions: a. During frequency , gain, input level changes, the vertical movement will raise or lower the number in the direction of the arrows.
b. For other functions such Mute on/off, the vertical switch will alternately turn the function on or off regardless of the direction operated.
2017-1351 Manual, Rev. B Page 16 09/14/17
2.5.4 Frequency Changes
At any time during the modification process, if you have made a mistake and do not wish to save the changes you have made, do not press the Menu/Execute switch; simply do nothing for approximately 12 seconds, and the system will return to the normal operating mode or scroll to “R” and push the menu/Execute switch and select “NO” in the “SAVE SETTINGS?” window.
To change the FREQUENCY:
Operate the Menu/Execute switch until you get to the menu item you want to change (see Figure 2.4 for the sequence of menu options). The following display is for changing the upconverter frequency:
UP F = 475 R
Pressing the Up/Down switch down will toggle the display to:
UP F = 575 R
By using the horizontal rocker switch the cursor can be moved left or right.
UP F = 575 R
NOTE: CHANGES DO NOT TAKE PLACE ON FREQUENCY UNTIL YOU GO TO THE SAVE
MENU AND INDICATE YOU WANT TO SAVE THE CHANGES.
When the display indicates the value desired you can push the Menu/Execute switch to the next item:
UP INLVL = -20 R
NOTE: CHANGES TAKE PLACE ON LEVEL AND GAIN IMMEDIATELY BUT DO NOT GET
SAVED UNTIL YOU GO TO THE SAVE MENU AND INDICATE YOU WANT TO SAVE THE
CHANGES.
OR you can scroll to “R”, push the Menu/Execute switch to get to:
SAVE SETTINGS?
Y N
Selecting Y will save the new settings. Selecting N will revert to the previous settings.
Pushing the Menu/Execute switch then takes you to the :
U F = 475 G=+10.0
D F = 140 G=+20.0
Figure 2.4 shows all the menu items and how to make changes.
